Permissions on filesMany online articles tell you to set permissions on files in order to make something work. Our file system is properly configured, and unless you are doing any advanced sharing of files across hosts - your directories only need 700 permissions, and your files need 600 to be usable by the web server.

chmod 600 [filename]
